Question

I'm trying to connect to my LDAP server via PHP, but I get the following error:

Fatal error: Call to undefined function ldap_connect()

Any help would be very appreciated.

Thanks in advance, roshan

Answer 1

Make sure the LDAP extension is installed and enabled. This answer assumes you have PHP5, however, things should work similarly for PHP7 as well.

Install LDAP Extension

There should be a package named like php5-ldap:

aptitude show php5-ldap
Paquet : php5-ldap
...
Description : LDAP module for php5                                                                                                                                                                                                           
 This package provides a module for LDAP functions in PHP scripts.

Thus, the package can usually be installed like:

sudo apt-get install php5-ldap

If you do not use apt-get, use the equivalent command for the package manager you use.

Enable LDAP Extension

To enable the package after installation, you can use this command:

sudo php5enmod ldap

If you get any error message from the above command, it means something went wrong.

Note: After enabling the package, you usually have to restart / reload services so that the newly enabled module is recognized. For apache, you can do this by:

sudo service apache2 restart

If you do not use apache, please use the equivalent command for your server.

Answer 2

sudo apt-get install php5-ldap

And don't afraid to google.
